“Boosting” Your Immune System?

February 1, 2011 · 3 Comments

For once, I am not sick with some massive cold, allergic reaction, or, for goodness sake, pneumonia, like I have been on and off for the past several months. Some people would encourage me to boost my immune system using megadoses of Vitamin C or some other “over the counter” remedy. In the new year, as an unofficial resolution, I am paying more attention to what nutrients and vitamins I’m getting from food, but is there really a way to help out your immune system?

Erik Davis at Skeptic North posted this excellent review of “immune boosting” supplements and the medical journals that have weighed in on them. Do go over and give it a read for some fascinating information. The bottom line is that there is no strong evidence of “immune boosting” techniques, even that Vitamin C myth that has been tested over and over again for 50 years. One actual way of boosting your immune system? Vaccines, of course.

Now eat your fruits and veggies and get off my lawn.

The Face in your Bellybutton

January 26, 2011 · 1 Comment

Somehow, I missed out on being part of an excellent experiment at SciOnline a few weeks ago. A group of scientists and science communicators have teamed up to explore the “wildlife of the body” through Belly Button Diversity. They took samples from bellybuttons of various conference participants and let them grow in an agar solution. Now, you can see some of the results!

Your own personal biosphere!

As I looked at these, patterns began to emerge. I began to see… faces…

Astrology "Shakeup"

January 16, 2011 · 4 Comments

Ironically, I am too wiped out to blog after Science Online 2011! It was all kinds of awesome.

So, to further follow-up on the astrology nonsense of the week, here is my boss and all around cool guy at Discovery, Ian O’Neill, debunking the astrology bunk on Fox News, while an astrologer says it has to do with interpretations and resonances, while the reporter just keeps getting things wrong. (e.g. Rotation is not precession.) Good times!

So what's your sign, baby?

January 13, 2011 · 3 Comments

I got a question about this from one of my dearest friends, and so I’ll take a bit of time to answer it here. In the infamous words of Charlie Tolbert at UVa, “Astrology is bunk.”

That’s it. That’s the bottom line. But we’re good skeptics so we’ll delve a little deeper.

(First though, I should note, I just discovered that there is a whole Facebook page called “Astrology is bunk” for students who have had the honor of taking Tolbert’s class. I never did technically, but I was his TA, and enjoyed the class greatly!)

Astrology is essentially the idea that the alignment of the stars and planets when you were born have some kind of effect on your life. But there are some holes in this hypothesis. First of all, only 7 “planets” were known to the ancients: Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. Astrological forecasting took those into account, but not Uranus and Neptune, which were there, but simply undiscovered. Wouldn’t a good astrologer have realized that something was off, and maybe even predict the existence of those planets long before they were spotted with telescopes. And what about Pluto? It was a planet and now it’s not, how has that ever been worked in?

You think they'd find the gas giants...

Next, there is the question of how the celestial objects affect you. The nuclear forces work over too short of a range, and the electromagnetic force isn’t very useful over large distances as well. Plus, astronomical objects are pretty much neutral anyway. So that leaves us with gravity. I could go through the derivation to show you that the gravitational pull of you mom’s obstetrician is comparable to that of the largest planet of our solar system, Jupiter, but that’s already been done. Note that his or her presence is not included in astrological forecasting. After 4 centuries of study with telescopes, there is nothing special about the planets or stars that would make them seem to affect our lives, and gravity isn’t it.

The topic of the current kerfuffle are the zodiac constellations. Typical Western astrology splits up the human population into 12 “signs” based on the constellation in which the sun was when that person was born. Note that these are specifically the ancient Greek constellations, as if they hold any special knowledge or significance to mysticism. As any good Astro 101 student can tell you, the Earth goes through a process called precession, in which the axis of the Earth slowly moves around a circlethe sky in a 26,000 year cycle. Therefore, celestial north isn’t always at the star Polaris, and was indeed pointed near bright Vega some long time ago. When you map the sun’s position against the background stars, it will change over time! Astronomers have to constantly upgrade their coordinates to keep up, yet Western astrology pays no heed to this, and your newspaper horoscope has the birth range for if you were born thousands of years ago!

July 31 means I'm a Leo! And look, there's the Sun in Leo! Except, I'm not 2000 years old...

The position of the sun on my actual birthday.

Well, apparently an astronomer in Minnesota (eh?) pointed this out to a reporter, and it morphed somehow into this huge DEAL where everyone is trying to recalculate their sign. Or, in some cases, refusing to change because they are so attached to it. It’s okay. I’ve been there. Though I was never really convinced of astrology’s supposed predictive powers, I relished the idea of being lion-like. Grrr. But really, it’s just silliness. The Christian Science Monitor has a really good article about this silliness, and includes the dates and the “13th zodiac sign” Ophiuchus. As they point out, this is not news to anyone who knows their way around the sky.

Finally, one could point out that science has found weirder things than we can dream up in our imaginations. Even if the mechanism seems absolutely implausible, does it work? The data say No. In a review of some 500 studies done on astrology since the 1950s, astrology fails over and over and over again to predict anything about a person. (It is really fascinating and I encourage you to check out the above-linked pdf.) In fact, you could give a whole room of people the same newspaper style horoscope reading and have most of them tell you, “Oh yeah, this sounds like me!” because they are written so generally.

So not only is astrology implausible and incorrect, it just plain doesn’t work. Unfortunately, that’s not the message that came across through the twisted world of the media.

Finally, if astrology does nothing, then what is the harm in belief? Most of the time, nothing. But pseudo-scientific thinking seems to have a way of causing damage in any case, as is cataloged by Tim Farley’s “What’s the Harm” website. Go ahead, check out the astrology section. Sucks, doesn’t it?

A great reference on astrology is on Phil Plait’s original Bad Astronomy website. Also, check out his take on the matter on his blog. Thanks also to Tim Farley’s SkepSearch for weeding out the nonsense.

SkepTales, Woo OOO ooo!

January 4, 2011 · Leave a Comment

(With apologies to Duck Tales.)

My recent skeptical confession prompted the bad-ass-ness himself, Phil Plait, to call for people’s skeptical stories on Twitter. The abbreviated format allowed for cleverness, rhyming, and some careful thought about what to say. The response was AMAZING. Almost 500 people shared their personal stories, from the “aha!” moment to the slow and thoughtful. Some talked about religion, others about the paranormal. Some held on to beliefs for many years; others figured it out in childhood. There are tales of self-discovery and inspiration, and I highly recommend you at least browse through them.

Also, I’d like to note that this post is the first in my attempt at WordPress’s PostADay2011 series. Yikes! That means I’ll be trying to get something up at least once a day (not just here, but on Discovery Space as well, almost every day). Many here will be short, Tumblr-like posts, but hey, it’s something. Hopefully, that’ll inspire me to go back to writing more frequent “meaty” posts. (Thanks for inspiration to AstroEngine!)

This will be especially interesting as I am traveling most of this month. Today starts my trip to Boulder, CO, for the URSI conference, and to catch up with friends. A few days after my return, it’s on the road again to Science Online 2011! And somewhere in between all that, I need to finish a dissertation year fellowship application. That’s right, there IS a light at the end of the tunnel for me, and it’s not an oncoming freight train…

My 2011 resolution? Continue to work on being as awesome as I can be.

Sagan Day 2010

December 29, 2010 · 2 Comments

So before 2010 actually ends, I promised a recap of the Carl Sagan Day in Florida that I attended in November. Sad that you missed it? Well, all of the talks are still archived on video! Since I actually missed many of the talks due to my other duties, I’m glad for that.

If you didn’t already know, Carl Sagan was a huge influence on my life, through the movie “Contact” which I saw in theatres just as I was rekindling an interest in astronomy, pointing me towards where I am today, and Demon-Haunted World, a book that really got me thinking about skepticism, or how to apply science to everyday life. So you can imagine my ridiculous thrill when I was asked to participate!

Overall, it was a very fun and busy event at which I met a lot of fabulous people that I unfortunately haven’t had the time to keep up with since then. (Hello!) I was a bit sad, however, by the realization that I never did get to meet Sagan himself and thank him for the tremendous impact he had on my life. However, I got to live a little bit through James Randi’s talk, the last one of the evening, about his friendship with Carl Sagan. I nearly fell out of my seat with laughter when he recalled a time when Carl was tired of filming in that “cardboard spaceship” all the time.

Spaceship of the Imagination, from Cosmos

It was really good to laugh and smile and celebrate the legacy that Sagan left behind. In the morning, I ran my first ever, brand-spanking-new teacher workshop, in the spirit of science education which Sagan upheld. Of course, I had to follow the excellent acts of Jeff Bennett, who has written some of my favorite astronomy textbooks and children’s books, and Jeff Wagg, who did freaking cards tricks! I think my ultraviolet-sensitive beads made for a good time as well, as I showed how they can demonstrate a blinded experiment in a fun (and sometimes messy) way.

The main event featured a series of speakers and was also live-streamed to all the fine folks on the interwebz. I had the honor of giving the first talk (ack!) which was a wandering history of the search for extraterrestrial intelligence, a project in which Sagan was deeply involved. Talk about nervous! Not only was it a pretty full lecture hall AND chat room, but James Randi was in the front row with the lovely Chip and Grace Denman who I had met through SkepticampDC. Eep! Afterwards, I lugged my suitcase full of astronomy demo goodies outside to do astronomy activities with the kids in attendance! We made comets, played with soda and Mentos, had a scale model solar system, and had facepainting. (I had no hand in that last one, it was all the skillful work of Gabrielle Stern! Unfortunately, I never got one myself, with all the running around and getting soda in my hair.)

Meanwhile, the main speakers were touching on more aspects of Sagan’s legacy, from skepticism to space flight, and again to alien life. In addition to the aforementioned Jeffs, Russell Romanella and the hilarious and insightful Hal Bidlack took the main stage. As it got dark, I was able to attend the last two talks, the first by my fellow “damn kid” (according to Bidlack), John Boswell, who composes the excellent Symphony of Science. We were even treated to a preview of “A Wave of Reason”, which has since been released. I am a huge fan of this project because it melds art and science, and it pulls forth such emotion, at least from me, and from many others as well. Who said skeptics and scientists are only about cold logic?! If this project isn’t in the spirit of Sagan’s work to share the wonders of the universe, I don’t know what is.

The final talk by Randi was a real treat. I can’t do it justice, other than fond remembrance of the poor, cardboard spaceship, so do watch that one if you get a chance. And THEN I got to finally meet The Amazing Randi himself, which made me all giddy-fan-girl. Just a little. For all his ferocity with fighting charlatans, he is a sweet man, and I hope to see him at TAM9! Sadly, I did not get a chance to get over to the JREF, as my time there was short. However, that night I learned that nerds + dry ice + beer = hilarity.

Giddy fan-girl with a bee

There are more pictures of me and (mostly) Buzznaut, one of our Dark Skies, Bright Kids mascots, on Flickr. The best part was when I showed this picture to the kids upon my return, and asked who they thought this man looked like. Expecting to hear “Santa Claus,” I was delighted when one fourth grader shouted, “He looks like Galileo!” Ladies and gentlemen of DSBK, I think we are doing a good job.

Please, someone with photoshopping skills, I want to see Jame’s Randi’s face on an illustration of Galileo with his telescope. Please, please, please!

With that, I encourage you to check the work of Carl Sagan and some of the many projects inspired by skepticism, science, and the sheer amazement at how cool our universe really is.

But wait, there’s more! Be sure to read Jeff Wagg’s comments on the day, and check out the special edition ceramic necklaces made by Surly Amy.

Jeff Wagg Remembers Carl Sagan…

November 12, 2010 · 2 Comments

… on the JREF Swift blog.

I have to add, I cannot for the life of me FIND my copy of Demon-Haunted World. It’s such a great book, and I probably lent it out to spread its message as much as I could… and don’t know where it is. One of these days I’ll have to pick up a new copy. Or keep borrowing my professor’s copy. (Thanks, Ed!)

Sagan Day was indeed a lovely event and great success. I’m glad that his work in science outreach and skepticism continues to this day with a vibrant (if cat-herding-like) community. If only I could have met the man and told him what an impact he had on my life, both in my career choice and my path to skepticism. Ah well, I can always go watch another episode of Cosmos, with the damn cardboard spaceship ;-)

I hope to share my own thoughts and pictures from the event when things settle down in a bit!

Beam Me Down the Rabbit Hole

October 14, 2010 · 2 Comments

On October 9th, 2010, I went down the rabbit hole. I went to a Mutual UFO Network conference.

… Thus begins my take on a very strange Saturday. Read the entire article over at SheThought!

Honoring Carl Sagan

September 23, 2010 · 5 Comments

In 1997, a pre-teen girl with a thick New York accent went to the movie theatre. Her parents knew she liked space and astronomy and aliens, so they took her to see a movie that had all those things, “Contact.” In the movie, another little girl by the name of Ellie decided at a young age that she wanted to study the stars, that it would be her life’s work. And the little New Yorker chick thought to herself, “Yeah, I could be an astronomer, too. I love the planets and stars and telescopes.” Luckily, she had an encouraging mom and teachers that helped her realize that goal.

I’m still on this path to becoming an astronomer when I grow up*, and Carl Sagan’s “Contact” was a big influence. Later, “Demon-Haunted World“** would lead me on a path to skepticism and “Cosmos” would show me just how beautiful the explanations of science can be.

So, I am beyond thrilled to be involved in the 2nd annual Carl Sagan Day in Florida this November 6th! It will be a day of teacher workshops, kids activities, and guest speakers on astronomy, space, education, skepticism, and the life of Carl Sagan who has been so influential to so many. If you can get to Ft. Lauderdale that weekend please do come to this free event. There will also be a fundraiser 5K on Sunday to raise money for science supplies for their local schools.

In addition to the chick with the headset, we’ll have Jeff Wagg, who has a cool new project called Indie Skeptics, and who I consider my BFF since he gave me a package full of pirate eyepatches at Dragon*Con, Jeff Bennett, astronomer, author, and teacher whose textbooks and kids books we love here at UVa, Alexander Hamilton… I mean Hal Bidlack, and Dawn (Elliott) Martin who works at NASA Kennedy Space Center, one of the coolest places in the world. AND, of course, The Amazing James Randi will be speaking! I STILL have yet to meet him, and I predict that I will make a fangirl fool of myself at some point. *SQUEE*

This event promises to be a lot of fun, but even if you can’t make it, be sure to share Carl Sagan’s work with someone and celebrate his legacy. Here’s a bit of Sagan for your day!

* Time TBD
** So, I find it odd that I can’t find two of the most influential books in my library, so if I lent either one to you, please let me know!
